6.9 Cautions When Using Timer Array Unit
6.9.1 Cautions When Using Timer output
Depends on products, a pin is assigned atimer output and other alternate functions. In this case, outputs of the other
alternate functions must be set in initial status.
(1) Using TO01 output assigned to the P16 for 20-pin products
So that the alternated SO11 output becomes 1, not only set the port mode register (the PM16 bit) and the port
register (the P16 bit) to 0, but also use the serial channel enable status register 0 (SE0), serial output register 0
(SO0), and serial output enable register 0 (SOE0) with the same setting as the initial status.
(2) Using TO02 output assigned to the P17 for 24- and 25-pin products
So that the alternated SO11 output becomes 1, not only set the port mode register (the PM17 bit) and the port
register (the P17 bit) to 0, but also use the serial channel enable status register 0 (SE0), serial output register 0
(SO0), and serial output enable register 0 (SOE0) with the same setting as the initial status.
(3) Using TO02 output assigned to the P17 for 20-pin products
So that the alternated SDA11 output becomes 1, not only set the port mode register (the PM17 bit) and the port
register (the P17 bit) to 0, but also use the serial channel enable status register 0 (SE0), serial output register 0
(SO0), and serial output enable register 0 (SOE0) with the same setting as the initial status.
(4) Using TO03 output assigned to the P31 for 24- to 44-pin products
So that the alternated PCLBUZ0 output becomes 0, not only set the port mode register (the PM31 bit) and the port
register (the P31 bit) to 0, but also use the bit 7 of the clock output select register 0 (CKS0) with the same setting
as the initial status.
